Here's how Intel describes the settlement:

Intel Corporation and Advanced Micro Devices today announced a comprehensive agreement to end all outstanding legal disputes between the companies, including antitrust litigation and patent cross license disputes.

Great. Well, sort of: Intel's biggest problems right now don't come from other companies, but from governments: complaints from AMD no doubt helped spur investigations by the European Commission and New York Attorney General into Intel's business practices, and as part of the agreement AMD is withdrawing their complaints with both agencies, but the EC issued their $1bn+ fine quite a while ago, and from the looks of it, the AG's office is eager to move forward with their investigation too. In other words, this probably isn't the end of the pain for Intel.

That, kids, is why you don't engage in anticompetetive practices in a two-company industry. [WSJ Law Blog]
